我需要从一组文件建立一个图表。我的脚本如下和输出。

import sys
import matplotlib.pyplot as plt
import matplotlib.image as img
import pandas as pd
import numpy as np
import glob

df=ReadMultPRYFiles(f"/data/beegfs/projects/XOMG2201-FLD/databases/orient/RL53744.00/RL*RP_15*")
# Define variables
X = df['x num']
Y = df['y num']
z = df['value']

# Plot the x, y, and z coordinates as a scatter plot with color representing z
plt.scatter(X, Y, c=z, cmap='rainbow', s=20, marker = 's',zorder=10)

# Y ticks frequency
plt.yticks(np.arange(min(Y), max(Y), 10))

# Add labels to the x and y axes
plt.xlabel('REC_X')
plt.ylabel('REC_Y')
# display
plt.show()

一切都很好，但我想看到的Y标签只有我实际上有价值，从15264至15808，没有插值或价值以外的范围。
